Why is it painful to lift a heavy load with a thin piece of string?

Physics
1 answer:
Aleksandr [31]3 years ago
5 0

Explanation:

A thin piece of string has lower force than of a heavy load.

When the load is being lifted, the force exerted by the load is much more greater than the string, which eventually hits our hands.

For example, a heavy bag. You tie a thin string to it and try to lift it. The force exerted by the bag will hit the string harder, reaching for your plams. As the thin string has less force, its reaction force is not enough to hit back the greater force. Also, the less the surface area, the more difficult the grip gets. But, if you attach a thick rope or belt, the force exerted my the bag is automatically minimized as the reaction force of the thick rope is near about the action force. Hence, greater the surface area, better the grip.

<em>*action force: force exerted by the bag</em>

<em>*reaction force: the force hit back by the rope</em>

ivann1987 [24]

Answer:

The minimum time, t = 21.11 m

Explanation:

Given,

The maximum distance between the Earth and Mars, d = 780,000,000 km

The maximum distance between the Earth and Mars, d = 780,000,000 km

The speed of the light, c = 300,000 km/s

The distance and speed of the object is related using the formula,

                           v = d / t

                            t = d / v

The minimum time it takes for data transmission is when the distance between the Mars and the Earth is at minimum.

Therefore,

                            t = 380,000,000 km / 300,000 km/s

                              = 1266.67 s

                              = 21.11 minutes

Hence, the minimum time it takes for data transmitted by the Mars Surveyor to reach earth, t = 21.11 minutes

Kenny klutz drops his physics book off his aunt's high-rise balcony.it hits the ground below 1.5 s later?
tatuchka [14]

Gravity causes a falling object to fall 9.8 m/s faster every second it falls.

Kenny's book started out with no speed when it was dropped. 
1.5 sec later, it was falling at (9.8 x 1.5) = 14.7 m/s .

During the fall, its average speed was  1/2(0 + 14.7) = 7.35 m/s .

Distance it covered = (average speed) x (time) =

                                             (7.35 m/s) x (1.5 sec) = 11.025 m
